Abstract

A water-soluble unit dose article containing a fibrous element. A first article and a second article that differ in relation to compositional and physical characteristics. The process for manufacturing such articles.

Description

The present disclosure relates to multiple water soluble unit dose articles and processes for producing such articles. The article may include fibrous elements and may differ in relation to compositional and physical characteristics.

Offering consumer products in water-soluble unit dose form is becoming more and more popular, in part because of its convenient and no-mess form. In particular, water-soluble articles containing fibrous elements may be particularly advantageous. For example, the activator may be packed into or on the fiber elements themselves, may be entangled with them, may be coated on the elements, or on a ply made from such elements. It may be deposited. In addition, the article may include more than one ply, which can increase the flexibility and / or effectiveness of the form. In addition, articles made from fibrous elements can have a relatively high content of active ingredient, i.e. content, as it does not require water or other solvents in very high concentrations.

A further advantage of this form is that different articles can be filled with different types or concentrations of activators to result in different effect profiles. However, when presented with various items, consumers may be confused as to which item to use for which task or at that time. For example, in a laundry situation, washing denim blue jeans with bleach-containing articles can be disastrous, providing articles containing quaternary softeners for the washing cycle of automatic washing machines. This can be inefficient, washing the laundry of a particular person in the family with an article containing one scent, with a different scent, or possibly without any scent for reasons of sensitivity. It may be desirable to wash the laundry of the person. The potential for confusion of choice is significant with respect to water-soluble fibrous articles, especially given the relatively new and unfamiliar form of water-soluble fibrous articles when serving various articles in a single container. There is a risk of becoming.

It is desirable to provide unit dose articles, especially those containing fibrous elements as described herein, in a manner that reduces such user confusion.

The present disclosure relates to water-soluble unit dose articles and processes for producing such articles. The article may include at least a first ply, the first ply containing a plurality of fibrous elements, each fibrous element comprising at least one filament forming material and optionally a surfactant.

More specifically, the present disclosure comprises a plurality of water-soluble unit dose articles, including at least a first article and a second article, and differences in composition between the first article and the second article. Containing and relating to a plurality of water soluble unit dose articles comprising a physical difference between the first article and the second article.

The present disclosure is also a process for treating the surface, in which the surface is brought into contact with water in which the first water soluble unit dose article is dissolved, and the surface is dissolved in the second water soluble unit dose article. It also relates to a process of contacting the first and second articles with different compositions and characterizing the first and second articles with physical differences, including the step of contacting with water.

In particular, the present disclosure relates to multiple unit dose articles having compositional and physical differences. Physical differences can act as information (cue) and help consumers distinguish between goods and their respective intended uses.

Such a distinction may be important if one or more of the articles contain an activator that is particularly suitable for a particular use, while the other does not. Similarly, certain articles may contain activators that are not particularly suitable for a particular use, which allows physical differences to serve as useful information to the user.

It may be advantageous to use certain articles in combination with each other. The use of such combinations may be simultaneous, for example, the user may combine articles having two different fragrance mixtures to provide a customized scent experience. In addition, or alternative, the use of the combination of articles may be sequential, eg, by the user, one article is used in the cleaning process and different articles (eg, shampoo and conditioner, or laundry detergent). And fabric softener) may be used in the conditioning process. If it is desirable to use two or more articles with a combination of different activators, the articles may be used together due to physical differences in the article, for example by shape, color, and / or symbol of design.

FIG. 1 shows a perspective view of a typical water-soluble unit dose article 1. Article 1 may include a first surface 2 and a second surface 4 opposite the first surface 2. The first surface 2 and / or the second surface 4 may each be independently substantially flat in the XY plane. Article 1 as a whole may be substantially flat in, for example, the XY plane. The XY plane may be determined as the plane of the article having the first and second maximum dimensions (eg, the longest dimension and the maximum width dimension of the article).

Article 1 may have an edge 6 in the XY plane. The article may have a thickness of 8 in the Z direction orthogonal to the XY plane.

Article 1 may include at least the first ply 10. The first ply contains a plurality of fiber elements 20. As described in more detail below, the fibrous element may include at least one filament forming material and optionally a surfactant. Article 1 may include one or less plies.

The article may include a second ply 12. The first ply 10 may be joined to the second ply 12. Although not shown in FIG. 1, article 1 may include a third ply 14 or an additional ply.

Article 1 may include a flange 16. The flange 16 may be located on the side 6 of the article 1. The flange 16 may be continuous or discontinuous around the article 1, preferably continuous. The flange 16 may be, for example, the residue of the manufacturing process from where the article 1 was cut from the web 100. In addition, or alternative, the flange 16 may be an edge seal in which the first ply 10 is joined to at least the second ply 12.

May be good.

FIG. 2 shows a top view of the water-soluble unit dose article 1 according to the present disclosure. Article 1 may have an edge 6 in the XY plane. The side portion 6 may define the shape.

As shown in the article of FIG. 2 in an exemplary fashion, article 1 may be characterized by a length 18 defined as the longest dimension of article 11 in the XY plane. Each article may be characterized by a width of 19 which is in the XY plane and is defined as the maximum dimension in a direction orthogonal to the length 18.

Article 1 may be sized and sized so that it is easy for an adult to hold or, otherwise, be handled with one hand.

Article 1 is from about 1 cm, or from about 2 cm, or from about 3 cm, or from about 4 cm, or from about 5 cm to about 20 cm, or up to about 18 cm, or up to about 15 cm, or up to about 12 cm, or about 8 cm. May have a length of up to 18. Article 1 may have a length 18 of about 5 cm to about 10 cm.

Article 1 may have a width of 19 from about 1 cm, or from about 2 cm, or from about 3 cm, or from about 4 cm to about 12 cm, or up to about 10 cm, or up to about 8 cm. Article 1 may have a width 19 of about 4 cm to about 8 cm.

The ratio of the length 18 of article 1 to its width 19 is about 3: 1 to about 1: 1, about 5: 2 to about 1: 1, or about 2: 1 to about 1: 1, or about 3: 1. It may be 2 to about 1: 1.

Article 1 may have a height or thickness of 8 from about 1 mm, or from about 2 mm, or from about 3 mm to about 20 mm, or up to about 15 mm, or up to about 10 mm, or up to about 7 mm. .. The thickness 8 may be less than about 20%, less than about 10%, or less than about 5% of the length. The thickness 8 may be at least about 1%, or at least about 3%, or at least about 5% of the length 18. Height, or thickness 8 measurements, are obtained according to the thickness test method described herein.

As described above, the article 1 may have an edge 6 in the XY plane. The flange 16 may be substantially parallel to the side portion 6. Since the flange 16 may be located where a plurality of plies 10 and 12 are joined to each other, the sealing region and / or the flange 16 may have a drawback that it is difficult to melt. Therefore, it may be preferable to select the article 1 having a shape having a relatively smallest side portion.

However, to maximize the size of article 1 (eg, to deliver the desired amount of activator) and / or to choose a shape that is mosaic (eg, to efficiently produce the article). However, it is still important. The area of the shape defined by the side 6 of the article 1 may be used as a substitute for the size of the article. Therefore, it may be advantageous to select an article shape that has a desirable ratio of the side portion 6 to the area of the shape defined by the side portion 6.

For example, article 1 has a length of 18 cm or less, 12 cm or less, or 10 cm or less (that is, the longest dimension), optionally 3 cm or more, 4 cm or more, or 5 cm or more, or 6 cm or more, and 3 : From 10 / cm or from 4: 10 / cm to 12:10 / cm or less, or 10:10 / cm or less, or 8:10 / cm or less, or 6: 10 / cm or less. It may have a ratio of the side portion to the area of the shape defined by the side portion (“side portion: area ratio”). As an example, an article having sides within a square shape of 10 cm on each side has a side of 40 cm, ^{an area of 100 cm 2} , and 0.4 / cm (40 cm / 100 cm ² = 4:10 / cm, or 0. It has a side: area ratio of 4 / cm). Without being bound by theory, if the edge: area ratio is too large (eg, greater than 1.2 / cm), the edge / edge seal area ratio is too large relative to the size of the article. This means that the performance effect may be inferior due to dissolution problems. If the side: area ratio is too small (eg, less than 0.3 / cm, or less than 0.4 / cm), the article may be too bulky to be conveniently handled. In short, it can be too large for a convenient unit dose manipulation. For similar reasons, it may be desirable to cap the maximum length (eg, less than 20 cm, less than 18 cm, less than 15 cm, less than 12 cm) so that the article can be conveniently used.

Article 1 is about 0.25 cubic centimeter (cc) to about 60 cc, about 0.5 cc to about 60 cc, about 0.5 cc to about 50 cc, about 1 cc to about 40 cc, about 1 cc to about 30 cc, about 2 cc to about 20 cc, It may have a volume of about 3 cc to about 20 cc, about 4 cc to about 15 cc, or about 4 cc to about 10 cc. In certain examples, the article may have a volume of about 3 cc to about 6 cc. In another example, the article may have a volume of about 20 cc to about 35 cc, or about 24 cc to about 30 cc.

Article 1 is about 50 g or less, about 40 g or less, about 30 g or less, about 25 g or less, about 20 g or less, about 15 g or less, about 10 g or less, about 7.5 g or less, about 5 g or less, about 4 g or less, about 3 g or less, It may have a mass of about 2 g or less, about 1.5 g or less, about 1.25 g or less, about 1 g or less, about 0.75 g or less, or about 0.5 g or less. In a particular example, the article is about 0.25 g to about 50 g, about 0.25 g to about 40 g, about 0.25 g to about 30 g, about 0.25 g to about 25 g, about 0.25 g to about 20 g, about 0. .5g to about 15g, about 0.5g to about 10g, about 0.5g to about 5g, about 0.5g to about 4g, about 0.5g to about 3g, about 0.5g to about 2.5g, or about It may have a mass of 1 g to about 2 g.

Often, the percentage of difference is determined using the smaller measurement as a reference (eg, a width of 4.5 cm is 50% greater than a width of 3 cm). Having different sized articles may be related, for example, to the size of the recommended dose of active substance contained therein. In addition, the larger size may indicate to the user that the article is suitable, for example, for large volumes of fabrics or heavily soiled fabrics.

Physical differences may be related to shape, as shown in FIG. The difference in shape may be a two-dimensional difference or a three-dimensional difference. For example, the side portion of the first article 1f may define the first shape, the side portion of the second article 1g may define the second shape, and the first shape and the second shape may be defined. The shapes are not the same. The first shape and / or the second shape can be any suitable shape, including standard geometric shapes such as circles, ellipses, squares, rectangles, rhombuses, pentagons, hexagons, and octagons.

As a further example, any kind of random pattern, including lines, circles, squares, stars, moons, flowers, animals, snowflakes, leaves, feathers, shells, and Easter eggs, among other possible designs. Can be mentioned.

The symbol of the article may be associated with one or more active ingredients within or on it. For example, the symbol mark may be associated with a perfume composition, which may provide the user with information about the expected scent. The pine tree pattern mark may indicate the scent of pine or forest, and the bunches of lemon may indicate the scent of citrus fruits. As another example, the symbol mark may be associated with a target surface on which one or more activators contained therein are suitable, for example, the bleach-containing article may depict a white shirt or toilet bowl. It may include the mark of the symbol. Such a display may help the user manually select the right item.

As shown in FIG. 9, the first article 1j may include the mark 82 of the first symbol, and the second article 1k may include the mark 83 of the second symbol. The first symbol mark and the second symbol marks 82, 83 may be complementary in some way. Complementary symbols provide the user with information to use the first and second articles together, either simultaneously or sequentially, when they are intended to be used together. , May be particularly useful.

For example, the first mark and the second marks 81, 82 may be partial marks, respectively, and form a complete mark when placed side by side (eg, heart 2). Create a complete heart with one half and see Figure 9. Similarly, "TI" and "DE" are spelled "TIDE"). The first mark and the second marks 82, 83 may be associated with each other or may be associated with each other (eg, flowers and bees).

The symbols of the symbols may form a predetermined order, for example, as shown in FIG. 10, each first article 1 m may include the number "1" or the letter "A". The second article 1n may include the number "2" or the letter "B". The marks of the predetermined order 82a, 83a may indicate the order in which the articles are used, and each article may contain activators, such as detergents and fabric softeners, which are used in the same order.

One of the first article and the second article may contain the symbol mark, while the other of the first article and the second article may not include the symbol mark. ..

Physical differences may be related to texture. The first article may have a surface that is relatively rougher than the corresponding surface of the second article, and the increased roughness makes the article suitable for heavily soiled fabrics, such as those resulting from handwork. May be shown to the consumer. The first article may have a surface that is relatively smoother than the corresponding surface of the second article, and the smoother article makes the article suitable for lighter fabrics such as delicate ones. May be shown to the consumer. In addition, or alternative, a smoother texture may provide an indication of the functionality of the article, eg, a smoother article, such as a conditioning silicone, a quaternary softening compound, or a cationic polymer. May be desirable in combination with conditioning agents. The texture may be more directly related to the type of surface on which the article is suitable. For example, the texture may be characterized by a depiction of the target surface, eg, a ridge depicting a picture of a T-shirt or toilet. The texture of the article may be similar to the texture of the target surface, for example silky fabric. Different textures may be provided by embossing the web or article, or by forming a parent web on a belt with the desired pattern. Such textured information can be particularly useful to visually impaired users.

Physical differences may be related to basis weight. The user can see that an article with a larger basis weight, for example, has a stronger detergency and / or is more suitable for a larger task. Relatedly, the physical difference may be related to density. Articles with relatively high densities may imply, for example, stronger detergency to the user.

Physical differences may be the result of compositional differences, directly or indirectly. For example, the first article containing the toning dye may appear blue or purple, and the second article not containing the toning dye may not have the appearance of the same color. Articles containing silicones, quaterns, or cationic polymers may have a smoother tactile feel compared to articles not containing similar components.

Process for Manufacturing Water-Soluble Unit-Dose Goods The present disclosure relates to the process for manufacturing water-soluble unit-dose articles. Broadly, the process includes preparing the water-soluble web 100 and cutting the web 100 into, for example, a mosaic pattern 102 to form a plurality of water-soluble unit dose articles 1, as shown in FIG. May include.

The process may include preparing the water soluble web 100. The web 100 may include a plurality of fiber elements 20. Each fiber element 20 may contain at least one filament forming material and optionally a surfactant. The fiber element 20 and its components are described in more detail above.

The web may include at least a first ply. The web 100 may include a second ply, or even a third ply. Multiple plies can be formed, at least in part, from a single parent material folded over itself to form the web 100. Multiple plies can be formed, at least in part, from a single parent material that has been cut and stacked on top of itself to form the web 100. The material can be flipped or rotated 180 ° in addition to folding and / or stacking. As mentioned above, the ply may include two or more layers.

As shown in FIG. 12, the web 100 can be located on an endless surface 110 such as a belt. The web 100 can be moved in the mechanical direction MD. The web may have a width in the lateral CD orthogonal to the mechanical MD in the plane of the endless surface 110.

The web 100 may include a central portion 104 in the mechanical direction MD near the centerline of the web 100. The web 100 may include side edges 106, 108 that are laterally CD away from the centerline.

The cutting device 115 can cut the web 100 into, for example, a mosaic pattern 102. The cutting device 115 may be a die cutter, for example, a rotary die cutter. The cutting device 115 may include a mosaic surface 117 corresponding to the mosaic pattern 102.

The unit dose article 1 can be formed by cutting the web 100 into a mosaic pattern 102. The resulting unit dose article 1 may be of the same size and / or shape. The resulting unit dose article 1 can have different sizes and / or shapes, as described in more detail above.

After cutting the web 100, at least some of the unit dose articles 1 can be separated and then packaged. Alternatively, some or all of the unit dose article 1 can remain at least partially connected. For example, the web 100 can be knurled or perforated between unit dose articles 1. Prior to use, the consumer can tear the article 1 or otherwise separate it and use it as intended. In the present disclosure, it is conceivable that "cutting" the web 100 may include nicking and / or perforating the mosaic pattern of the web 100.

As shown in FIG. 12, the portion 120 of the web that does not form a unit dose article can be removed. The portion 120 of the web 100 can be removed and then the web 100 can be cut into a mosaic pattern 102. The web 100 can be cut with a cutting tool such as a rotary blade 116. The portion 120 to be removed may be near the side edges 106, 108 of the web 100, which gives the remaining web trimmed edges 107, 109. Trimming the web 100 in this manner may be useful in preparing a more uniform web 100 and then cutting the web 100 into unit dose articles 1. For example, the web 100 may be relatively thinner near the side edges 106, 108 as compared to the central portion 104, which gives the web 100 and / or article 1 with non-uniform calipers. This may require additional handling or may result in product variability. As a result of the removal or trimming step, the width of the web 100 measured from the trimming edge 107 to the trimming edge 109 measured on the lateral CD is the web measured from the (untrimmed) side edge 106 to the side edge 108. It is narrower than the width of 100.

The portion 122 can be removed after cutting the web 100 in a mosaic pattern. Such a portion 122 can be located near the side edges 106, 108 and / or the finished edges 107, 109. If the portion 122 is not suitable for sale as a finished product, such as the unit dose article 1, it may be desirable to remove the portion 122 after cutting. Such portion 122 may be an extra trim to be discarded or recycled. Mosaicization according to the present disclosure is believed to be useful in minimizing such portions 122. In particular, it is expected that such trim will be removed from the central portion 104 of the web 100 after cutting with little or no.

The web 100 can be pre-manufactured (ie, at different times and / or locations). The web 100 can then be fed onto the endless surface 110.

The web can be manufactured as part of the continuous article manufacturing process. Therefore, the process of the present disclosure may include a web forming step. Forming the web in a continuous process can be advantageous as it does not store and / or transport prefabricated webs. For example, the fiber element 20 can be deposited on the endless surface 110 moving in the mechanical direction MD in the fiber element stream 21 to form the web 100. The process may include providing a solution of the filament forming composition 130. The filament forming composition 130 can be passed through one or more die block assemblies 140, which may include a plurality of spinnerets, to form the plurality of fiber elements 20. Optionally, a plurality of filament-forming compositions can be fed by a single die-block assembly 40 to a portion thereof, or a plurality of filament-forming compositions can be fed to a plurality of die-block assemblies. Multiple die block assemblies can be useful if you want more than one layer within the web 100 or ply.

The fibrous element of the present invention can be produced from the filament forming composition. The filament forming composition may be a polar solvent-based composition, preferably an aqueous composition. The filament forming composition may contain from about 10% to about 80% by weight of polar solvent, such as water. The filament forming composition may be an aqueous composition containing one or more filament forming materials and one or more activators.

The filament forming composition comprises one or more mold release agents and / or lubricants such as fatty acids, fatty acid salts, aliphatic alcohols, aliphatic esters, sulfonated fatty acid esters, aliphatic amine acetates, and fatty acid amides, silicones. Aminosilicones, fluoropolymers, and mixtures thereof may be included. The filament-forming composition comprises one or more anti-blocking agents and / or tack removers such as starch, modified starch, crosslinked polyvinylpyrrolidone, crosslinked cellulose, microcrystalline cellulose, silica, metal oxides, calcium carbonate, talc, etc. And may include starch.

Filament-forming compositions of fiber materials using suitable spinning operations and / or spinning processes, including spunbonding, melt blowing, electrospinning, rotary spinning, continuous filament production, and / or bundle fiber production operations / processes. It can be formed from objects. For example, the filament forming composition can be spun into multiple fibrous elements by melt blowing. The filament forming composition can be pumped from the tank to the melt blow spinneret. Upon exiting one or more of the filament forming holes in the spinneret, the filament forming composition can be reduced in diameter by air to produce one or more fiber elements and / or particles. The fiber elements can then be dried to remove any residual solvent used for spinning, such as water.

The spinneret comprises multiple fibrous element forming holes, including molten capillaries, surrounded by concentric dampening fluid holes that allow fluid, such as air, to pass at a temperature of about 10 ° C to about 100 ° C, through the filament forming composition. When the filament forming composition exits the fiber element forming hole, the diameter of the filament forming composition can be easily reduced to the fiber element. The filament forming composition can be provided to the fiber element forming holes at a rate of about 0.1 g / min to 2 g / min per hole, which can be set based on the composition of the filament forming composition.

The process adds the particles 30 to the web 100, for example, by combining the particles 30 with the fiber element 20 in depositing as the fiber element stream 21 on the endless surface 110 moving in the mechanical direction MD. That may be included. In addition, or alternative, the process may include adding the particles 30 to the web 100 after placing the fiber element 20 on the endless surface 110. Prior to combining the particles 30 with the fiber element 20 and / or the web 100, the particles 30 may be in the form of a particle slurry 131. The particle slurry 131 can be passed through one or more die block assemblies 141.

The fibrous elements and / or particles of the invention can be recovered on an endless surface such as a belt, such as a patterned belt or flat belt, to form the ply 10 or web 100.

Although not shown in FIG. 9, the web 100 can be modified before or after the step of cutting the web 100 into unit dose articles 1. The active ingredient can be added to the web, for example, by spraying, brushing, coating, and / or applying beads of the composition containing the active ingredient. The active ingredient can be added in a continuous manner, which can be advantageous because intermittent addition of the ingredient can lead to registration problems, cutting the web. This is because sometimes the result is that article 1 is inconsistent. Cutting the web 100 into a mosaic pattern 102 can help reduce the waste of these active ingredients in addition to reducing the waste of the web material itself (eg, the fiber element 20).

If the web 100 includes at least the first and second plies 10, 12, the process may further include joining at least the first ply 10 and the second ply. The step of cutting the web 100 and joining the first and second plies 10 and 12 can be performed in a single step or operation. For example, the cutting device 110 such as a die cutter can be configured to cut the web 100 and at the same time join or seal the plies 10 and 12 together. For plies, optionally by using bond rolls, or by thermal bonds, calendar bonds, point bonds, ultrasonic bonds, infrared bonds, air bonds, needle punches, water confounding, melt bonds, adhesive bonds, or materials. It can be joined by other known technical techniques for joining plies.

If the web 100 contains at least two plies, cutting the web 100 and joining at least the first and second plies can be done in the same process. The plies can be joined together and die-cut in a single step using a single rotary coupling device and die cutting device.

It can be printed on the web 100 and / or the unit dose article 1. For printing, laser jets, inkjets, gravure, pads, rotary gravure, flexo, offset, screens, lithographs, or any other printing method suitable for printing a web of materials, especially the most suitable process for non-woven materials.

Test Method Thickness Test Method The thickness of the fiber structure and / or the height of the article is determined by using a ProGage Shockness Tester (Thwing-Albert Instrument Company (West Berlin, NJ)) with a circular pressure foot diameter of 2.00 inches. (3.14 inch ² area), measured at a pressure of 15.5 g / cm ^2. Five (five) samples are prepared by cutting the fibrous structure sample so that each cut sample is larger than the pressure foot surface and free of wrinkles, creases, and obvious defects. If the article has a length or width smaller than the diameter of the pressure foot, a smaller diameter pressure foot may be used, while appropriate so that a pressure of ^{15.5 g / cm 2 is still applied.} Make various adjustments. The individual samples are placed on the anvil so that the samples are centered under the pressure foot or at the maximum height position of the article. Lower the pressure foot at 0.03 in / sec until a pressure of 15.5 g / cm ^{2 is applied.} Read after a residence time of 3 seconds to raise the pressure foot. The measurement is repeated in the same manner for the remaining four samples. Thickness or article height is calculated as the average thickness of the 5 samples and reported in 0.01 mm increments.

Diameter test method The diameter of a discrete fiber element or a fiber element in a fiber structure is determined using a scanning electron microscope (SEM) or an optical microscope and image analysis software. Select a magnification of 200-10,000 times to properly magnify the fiber elements for measurement. When using SEM, the sample is sputtered with a gold or palladium compound to avoid charging and vibration of the fiber elements in the electron beam. Manual procedures are used to measure the diameter of fiber elements from images (on monitor screens) obtained using SEM or light microscopy. Use the mouse and cursor tools to find the edge of a randomly selected fiber element, then the other edge of the fiber element over its width (ie, perpendicular to the direction of the fiber element at that point). Measure up to. A calibrated image analysis tool with graduations provides graduations to obtain actual readings in μm units. For fibrous elements within the fibrous structure, some fibrous elements are randomly selected from the entire sample of fibrous structure using SEM or light microscopy. At least two parts of the fiber structure are cut out and tested in this way. For statistical analysis, such measurements are performed at least 100 times in total, and then all data are recorded. The recorded data are used to calculate the mean (mean) diameter of the fiber element, the standard deviation of the diameter of the fiber element, and the median diameter of the fiber element.

Another useful statistic is to calculate the amount of set of fiber elements below a certain upper limit. To determine this statistic, program the software to count how many of the fiber element diameter results are less than the upper bound, and then count that count (divide by the total number of data and multiply by 100%). , Recorded as a percentage below the upper limit (eg, percentage with a diameter less than 1 micrometer or submicron%). We represent the diameter (in μm) measured for each circular fiber element as di.

When the fiber element has a non-circular cross section, the measured value of the diameter of the fiber element is determined as the hydraulic diameter and is set to be equal to the hydraulic diameter. The hydraulic diameter is obtained by multiplying the cross-sectional area of the fiber element by four and dividing by the peripheral length of the cross section of the fiber element (in the case of a hollow fiber element, the outer peripheral length). The number-average diameter, or average diameter, is calculated as follows:

Medium Particle Size Test Method It is necessary to use this test method to determine the median particle size, which, as used herein, refers to the volume weighted average particle size.

The particle size is measured using an Accuser 780A manufactured by Particle Sigmaning Systems (Santa Barbara CA). The instrument is calibrated from 0 to 300 μm using the Duke particle size standard. As a sample for particle size evaluation, about 1 g of an emulsion (when determining the volume-weighted average particle size of the emulsion) or 1 g of a capsule slurry (when determining the volume-weighted average particle size of the final capsule) is approximately 5 g. It is prepared by diluting with deionized water of the above and further diluting about 1 g of this solution with about 25 g of water.

Using the automatic dilution function, about 1 g of the most diluted sample is added to the Accuser and the test is started. The Accuser needs to read above 9200 counts / sec. If the count is less than 9200, additional samples need to be added. Accuser dilutes the test sample to 9200 counts / sec and begins evaluation. Two minutes after the test, the Accuser displays the results including the volume-weighted median size.

Particle size exceeding 95% of cumulative particle volume (95% size), particle size exceeding 5% of cumulative particle volume (5% size), and volume-weighted median particle size (50% size-particles exceeding this size) The broadness index can be calculated by determining (both the volume and the particle volume below this size are 50% of the particle volume).
Broadness index (5) = ((95% size)-(5% size) / 50% size).

Basis weight test method Using a precision plate chemical balance with a sensitivity limit of ± 0.001 g, 12 usable units are stacked to measure the basis weight of the fiber structure. Use a windshield to protect the balance from airflow and other disturbances. All samples can be prepared using precision cutting dies measured at 3.500 "± 0.0035" x 3.500 "± 0.0035".

A sample is cut into squares using a precision cutting die of suitable size. The cut squares are put together and stacked to a thickness of 12 samples. The mass of the stacked samples is measured and the results are recorded in units of 0.001 g.

The basis weight is calculated at lbs / 3000ft ² or g / m ^{2 as follows.}
Basis weight = (mass of stacked samples) / [(area of one square in stacked samples) x (number of squares in stacked samples)]

Results are reported in units of 0.1 lbs / 3000 ft ² or 0.1 g / m ^2. Sample dimensions may be modified or varied using precision cutters similar to those described above so that the area of the stacked samples is at least 100 square inches.

Edge Seal Width Five positions of the edge seal flange are randomly selected for a given unit dose article. The linear distance of the seal of the test piece specified as the seal dimension "X" in FIG. 2 of ASTM F88 / F88M-09 is measured and recorded in 0.1 mm increments. The statistical mean of the five measurements is reported as the edge seal width.
